ALEXANDER SIMPSON AND JAMES B. ALVORD, OF SORANTON, PENNSYL- V ANIA.

, COAL-BREAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 432,446, dated July 15, 1890.

Application filed March 22, 1890.

To all whom it may concern.-

Be it known that we, ALEXANDER SIMPSON and JAMES B. ALVORD, of Scranton, in the county of Lackawanna and State of Pennsylvania, have invented certain new and useful Improvements in Coal- Breaking Machines; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains to make andnse the same.

Our invention relates to an improvement in coal-breaking machines, the obj ectof the same being to provide a machine of this character, by means of which the waste or pickings'of coal may be utilized and rendered of commercial value, thereby greatly enhancing the importance of mine outputs and at the same time supplying the market with a necessary article at greatly-reduced cost.

A further object is to provide a machine of this character, by means of which the waste arising from the loss of coal in dust will be reduced to a minimum.

A further object is to provide a machine of the above character, which will be simple and economical in construction and durable and efficient in use.

With these ends in view our invention consists in the certain features of construction and combinations of parts, as will be hereinafter fully described, and pointed out in the claim.

In the accompanying drawings, Figure 1 is plan View of the machine. Fig. 2 is a side view of the machine. Fig. 3 is a vertical longitudinal section. Fig. 4 is a detail view of one of the toothed plates.

A represents the horizontal supports, to which is secured the platform B by means of the standards 0, which pass through the platform and supports and are suitably secured thereto. To the bottom of the platform B is attached the plate D, which is provided with the screw-threaded bolt-hole E to receive the threaded regulating-rod F, which is preferably provided with a recess G, forming a bearing for the lower end of the j ournal-rod H. If desired, however the rod F may be pointed,

and the rod H provided with a recess to receive said rod F. The opposite end of said journal-rod H is provided with the tapering head I, and is journaled eccentrically in the disk or crank K, whereby an eccentric gyratory' movement is imparted to it. To the journalrod is secured the cone L, carrying the burred plates M, set thereon in section, so that they may be removed and replaced without loss of the entire cone. In the bottom of the platform B is secured the conical shell N, the same being formed of a series of toothed plates 0, the teeth of which are sharpened at the points and edges. The plates 0 are secured in suitable mortises P, formed in the platform B, their upper ends being held in place on the frame Q by means of the oblique shoulder R, formed thereon. The advantage arising from having the plates M removable is, that when they are broken or worn they may be readily replaced and when the edges become dull they may be removed for sharpening. The center frame S is provided with the internal bevel-gearing T, with which meshes the bevel-gearing U on the j ournal-rod H.

The disk K is keyed to the, rod V, which is journaled in the upper frame a. The rod W has secured to the top thereof the bevel gearwheel I), meshing with a similar Wheel 0 on shaft d, the said shaft being journaled in suitable bearings in the standards 6. A drivepulley f and fly-wheel g are keyed to said shaft.

The operation is as follows: The machine in motion will cause the disk K to revolve, carrying with it the journal-rod H, which will have an eccentric or wabbling movement imparted thereto, which is likewise imparted to the cone L, which is accomplished by means I, the bevel-wheel u, and the fixed internal 0f the rod F, the frames Q, S, and a being beveled rack T, substantially as set forth. suitably adjusted to conform therewith. In testimony whereof we have signed this Having fully described our invention, what specification in the presence of two subscrib- 5 we claim, and desire to secure by Letters Pating Witnesses.
